SHJ Series Row-level Precision Air Conditioner

SHJ Series Row-level Precision Air Conditioner

High-efficiency Spot Cooling for High-density Racks, Modular and Container Data Centers

1. Product Introduction

      Our SHJ series row-level precision air conditioner is engineered exclusively for high heat-density server rooms, modular data centers and containerized IDC facilities. Adopting in-row layout close to rack heat sources, it shortens air supply & return paths and raises return air temperature, delivering dynamically adjustable cooling output based on real-time IT load with outstanding high sensible heat ratio and energy efficiency.

      Equipped with full variable-frequency compressor and electronic expansion valve for precise throttling, its cooling capacity can be adjusted steplessly from 30% to 100%. A 7-inch colorful touch screen displays full component operation data, supporting intelligent cluster linkage of up to 32 units to stabilize temperature across an entire micro-module zone. 

      EC fan speed can be adjusted dynamically according to heat load with multiple control modes for maximum energy saving. Standard RS485 communication port and built-in water leak alarm enable seamless integration with UPS and central environment monitoring systems. Two cabinet widths (300mm and 600mm) are offered for flexible installation.

2. Core Technical Advantages

2.1 In-spot In-row Cooling Eliminates Rack Hotspots

      Mounted alongside server racks to minimize cold air transmission loss and shorten air circulation loop, it fits cold aisle containment perfectly and solves the common pain point of uneven heat accumulation on remote racks caused by traditional room-level CRAH units.

2.2 Wide-range Variable Cooling with High Sensible Performance

      Full inverter design paired with precise electronic expansion valve realizes 30%-100% cooling output adjustment to match fluctuating IT workload. High sensible heat ratio cuts redundant dehumidification consumption and optimizes long-term PUE performance.

2.3 Centralized Cluster Management for Up to 32 Units

      The local touch HMI aggregates operation data of all connected units, balancing cooling distribution across the whole rack row and preventing unit overload or uneven temperature zones.

2.4 Energy-optimized Dynamic EC Fan Control

      Fan rpm changes in real time following room heat load with optional control logics, cutting power draw under partial load and delivering much better energy efficiency than fixed-speed in-row AC products.

2.5 Built-in Monitoring & Water Leak Protection

      The RS485 interface connects to centralized O&M platforms for remote parameter setup and fault alerts; integrated water leak detection triggers early warnings to safeguard rack IT hardware and UPS power assets.

2.6 Two Width Options for Diverse Sites

      300mm slim version and 600mm standard version suit new modular data center construction, legacy server room retrofitting and narrow-space container data center deployment.

      All operation data of every unit under the SHJ series row-level precision air conditioner can be merged into your existing UPS and environment management dashboard.

3. Target Application Scenarios

   ● High-density server rooms

   ● Modular and micro-module data centers

   ● Containerized integrated data centers

5. Key Commercial Values for Operators

     1.Hotspot elimination reduces downtime risks of servers and UPS units caused by overheating, ensuring continuous core business operation

     2.Triple energy-saving design (inverter + EC fan + high sensible ratio) effectively lowers data center PUE and annual cooling electricity cost

     3.32-unit cluster control reduces manual workload for decentralized equipment maintenance

     4.Dual cabinet width enables flexible deployment for new builds, renovation projects and container IDCs

     5.Native data integration with UPS and monitoring systems realizes unified management of power supply, cooling and physical security

      For global high-density colocation zones and edge modular IDC projects, the standardized SHJ series row-level precision air conditioner unifies cooling architecture across multi-location facilities.

6. FAQ

Q1: Can multiple SHJ units work as a clustered cooling system for micro-modules?

A: Yes, the system supports intelligent linkage for a maximum of 32 units, automatically balancing cooling load for the whole modular zone. Our technical team will work out proper unit quantity and layout plan for your site when selecting the SHJ series row-level precision air conditioner.

Q2: Is third-party UPS and monitoring platform integration supported?

A: Standard RS485 communication is reserved for connecting mainstream UPS brands and data center O&M systems for remote monitoring and alarm notification.

Q3: Which width option should I choose for my project?

A: 300mm slim model fits narrow aisle and container data center, while 600mm model is for standard rack rows; our engineers can recommend the right dimension based on your on-site layout.

Q4: Does the unit have built-in water leak detection?

A: Water leak alarm is standard configuration to send early alerts and avoid hardware damage from condensed water seepage.
